This book presents the numerous tools for the econometric analysis of time series. The text is designed with emphasis on the practical application of theoretical tools. Accordingly, material is presented in a way that is easy to understand. In many cases intuitive explanation and understanding of the studied phenomena are offerd. Essential concepts are illustrated by clear-cut examples. The attention of readers is drawn to numerous applied works where the use of specific techniques is best illustrated. Such applications are chiefly connected with issues of recent economic transition and European integration. The outlined style of presentation makes the book also a rich source of references. The text is divided into four major sections. The first section, "The Nature of Time Series?, gives an introduction to time series analysis. The second section, "Difference Equations?, describes briefly the theory of difference equations with an emphasis on results that are important for time series econometrics. The third section, "Univariate Time Series?, presents the methods commonly used in univariate time series analysis, the analysis of time series of one single variable. The fourth section, "Multiple Time Series?, deals with time series models of multiple interrelated variables. Appendices contain an introduction to simulation techniques and statistical tables.

As organizations grapple with the challenges of a dynamic market, the integration of Artificial Intelligence (AI) emerges not only as a technological progression but a strategic necessity. The transformative potential of AI, particularly through OpenAI, holds the promise of redefining operational paradigms, accelerating innovation, and unlocking unprecedented growth opportunities. However, lurking beneath this promise are challenges that demand urgent attention – from tailoring relevance for specific business units to ethical and safe integration practices. The specifics of how OpenAI can amplify labor productivity and enhance decision-making processes remain elusive. Generative AI and Multifactor Productivity in Business offers a guide surrounding the complexities of OpenAI's role in business operations. It contends that understanding OpenAI is not just beneficial; it is essential for organizations seeking to navigate economic uncertainties and unlock high levels of efficiency and growth. The book delves into the effects of OpenAI on business, with a primary objective of illuminating the scholarly and practitioner-based contributions that push the boundaries of OpenAI in business research. This exploration encompasses applications of advanced generative AI tools, language models, and innovative technologies specific to diverse businesses across sectors, scales, and regions. It emphasizes that as AI becomes more seamlessly integrated into business processes, the potential for multifactor productivity to fuel economic growth, new industries, and job opportunities is unparalleled.

Exponential smoothing methods have been around since the 1950s, and are still the most popular forecasting methods used in business and industry. However, a modeling framework incorporating stochastic models, likelihood calculation, prediction intervals and procedures for model selection, was not developed until recently. This book brings together all of the important new results on the state space framework for exponential smoothing. It will be of interest to people wanting to apply the methods in their own area of interest as well as for researchers wanting to take the ideas in new directions. Part 1 provides an introduction to exponential smoothing and the underlying models. The essential details are given in Part 2, which also provide links to the most important papers in the literature. More advanced topics are covered in Part 3, including the mathematical properties of the models and extensions of the models for specific problems. Applications to particular domains are discussed in Part 4.

Presents original and up-to-date studies in unobserved components (UC) time series models from both theoretical and methodological perspectives.

Econometrics is the combined study of economics and statistics and is an 'applied' unit. It is increasingly becoming a core element in finance degrees at upper levels. This first local adaptation of Wooldridge's text offers a version of Introductory Econometrics with a structural redesign that will better suit the market along with Asia-Pacific examples and data. Two new chapters at the start of the book have been developed from material originally in Wooldridge's appendix section to serve as a clear introduction to the subject and as a revision tool that bridges students' transition from basic statistics into econometrics. This adaptation includes data sets from Australian and New Zealand, as well as from the Asia-Pacific region to suit the significant portion of finance students who are from Asia and the likelihood that many graduates will find employment overseas.

For the last four decades, the uses of econometric tools and techniques, irrespective of discipline, have been increasing rapidly for solving problems, appropriate decision-making and policy formulation. Generally, it is accepted that the study of modern business and economics is incomplete without a proper knowledge of econometric tools and techniques. In view of the increasing complexity and variety of problems in business and economics, students and researchers may not be able to cope and hence may remain unfamiliar with many aspects of business and economic problems. Thus, this book was written to explore basic and advanced studies of econometrics for undergraduate and graduate students of business and economics, as well as for researchers already engaged in these fields who require an introduction to econometric methods and their application for solving of real-life problems. The book offers a balanced presentation of fundamental and advanced levels of econometric concepts and methods, along with practical examples of their effective application in real-life problems.
